David Royel was born on 4 July in Chicago, Illinois to Koresh and Flourence Royel. He is a first-generation Assyrian American. His involvement in the Assyrian Church of the East began at a very young age. At 16, he was ordained as a subdeacon, and the following year became a deacon. He was ordained by Mar Dinkha IV. Both ordinations took place at Mar Gewargis Cathedral (St. George Cathedral) in Chicago.^{[citation needed]}

David Royel was ordained as Cor-Bishop on 15 July 2006 by Mar Dinkha IV at Mar Gewargis Cathedral in Chicago, Illinois, and as Archdeacon by Mar Dinkha IV on 23 November 2008 in Mar Yosip Khnanisho Church in San Jose, California.^{[citation needed]}

On 30 November 2008, David Royel was elevated to the rank of Bishop, taking the name Mar Awa Royel – in Assyrian, Awa means father. He is the first American-born Bishop of the Assyrian Church of the East. Mar Awa was again consecrated by the Patriarch Mar Dinkha IV, assisted by Mar Sargis Yousip, Bishop of Iraq, Mar Aprim Khamis, Bishop of the Western United States, and Mar Odisho Oraham, Bishop of Europe. The ordination ceremony took place at St. Zaia Church in Modesto, California, attended by over 2,500 members of the Assyrian Church of the East, and broadcast on Assyrian National Broadcast.^{[citation needed]}

On 6 September 2021, Mar Gewargis III formally stepped down as Catholicos-Patriarch during an Extraordinary Session of the Holy Synod of the Assyrian Church of the East, leaving the Patriarchal See vacant. On 8 September 2021, the Holy Synod elected Mar Awa Royel, Bishop of California and Secretary of the Holy Synod, to succeed Mar Gewargis III as the 122nd Catholicos-Patriarch of the Assyrian Church of the East.^[8][9] This was a historic decision as Mar Awa was the first Western-born Catholicos-Patriarch. He was consecrated and enthroned as Catholicos-Patriarch on 13 September 2021, on the Feast of the Holy Cross, in the Cathedral Church of St. John the Baptist in Erbil, Iraq, and assumed the ecclesiastical name Mar Awa III.^{[citation needed]}
